How can we change the alias of our website?

Hi, we recently changed the name of our Club and would like to change the alias of our website accordingly. I read that the alias can be changed in the box marked "Website Alias" in the Admin Console, but I can´t find that box. Is there any other way to change the alias? Attached is the admin menu that I am seeing.

Click on the "Launch Admin Console" button... scroll down in the dialog that shows to find the alias entry field and enter the new alias there.   Be advised that the change occurs immediately and you will be logged out.  You will need to navigate back to your website using the new alias and log back in.

Thanks so much, it worked!
